A unique blend of activators, rectifiers, catalysts, penetrants and wetter’s for hot black oxide stainless steel. This patented formulation is recommended for black oxide installations where it is desired to automate the replenishment additions of the blackening salt solution through a pump and liquid level control system. It is also ideal for the initial charging of black oxide baths, which will be replenished with our conventional, dust-free Black-Magic SS C salt.
